Description

Technical Field

[0001] This utility model relates to the field of biocontrol bacteria propagation technology, specifically to a self-propagation system for biocontrol bacteria in crops. Background Technology

[0002] Crop biocontrol microbial self-propagation systems are agricultural technologies that utilize biological control methods, particularly by cultivating and propagating beneficial microorganisms (such as biocontrol bacteria) on crops to control plant diseases. The core idea of ​​this system is to use these beneficial microorganisms (such as fungi and bacteria) to inhibit or kill pests or pathogens, thereby reducing reliance on chemical pesticides and promoting more eco-friendly agricultural production methods. Specifically, biocontrol bacteria can compete with pathogens for space and nutrients, inhibiting their growth. Some biocontrol bacteria directly parasitize pests or pathogens, causing their death. Biocontrol bacteria can also stimulate the plant's immune system, enhancing its ability to resist diseases.

[0003] Most biocontrol bacteria self-propagation systems operate within specific containers, utilizing kitchen waste or leftover fruits and vegetables. Organic kitchen waste, such as fruit and vegetable scraps, kitchen garbage, or agricultural residues like straw and fallen leaves, is typically rich in organic matter, providing a nutrient base for the biocontrol bacteria. This waste is then added to the container, slurried, and then suitable biocontrol bacteria inoculants are added. These inoculants can be liquid, powdered, or spore-based preparations. After mixing, the materials need to be thoroughly stirred to ensure the biocontrol bacteria are evenly distributed throughout the waste. Stirring not only helps the bacteria adapt to the environment but also improves gas exchange, ensuring the bacteria's growth needs are met. After fermentation, the number of biocontrol bacteria increases significantly, gradually accumulating in the waste to form an active microbial community.

[0004] However, in existing biocontrol bacteria self-propagation systems, the bacteria, viruses, and other microorganisms in the internal materials often affect the growth and reproduction of the biocontrol bacteria during the introduction of the inoculum, including resource competition, direct inhibition, and environmental changes. Therefore, to solve the aforementioned problems, a biocontrol bacteria self-propagation system for crops is provided. Utility Model Content

[0005] The purpose of this invention is to provide a self-propagation system for biocontrol bacteria in crops to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a self-propagation and reproduction system for biocontrol bacteria in crops, comprising a cylinder, the interior of which is used to fill materials and bacterial strains;

[0007] The mounting tube is vertically and fixedly connected to the inner wall of the cylinder. The mounting tube is made of transparent material and the interior of the mounting tube is used to house the ultraviolet lamp tube.

[0008] An air chamber is opened inside the end face of the installation tube. Multiple one-way exhaust pipes communicating with the air chamber are fixedly connected to the lower end of the installation tube. The installation tube is connected to the ozone generator pipeline, and ozone is discharged from the one-way exhaust pipes through the air chamber.

[0009] As a preferred technical solution of this utility model, multiple installation tubes are provided, and the multiple installation tubes are evenly distributed in a ring array, with air pipes connecting the multiple installation tubes.

[0010] As a preferred technical solution of this utility model, the trachea includes a ring pipe, a connecting pipe and a guide pipe. Multiple connecting pipes are uniformly and fixedly connected to the outer wall of the ring pipe in a ring array, and the other end of the connecting pipe is fixedly connected to the end face of the mounting pipe. The guide pipe is also fixedly connected to the outer wall of the ring pipe, and the other end of the guide pipe penetrates the upper end face of the cylinder.

[0011] As a preferred technical solution of this utility model, the upper end of the installation tube penetrates the upper end surface of the cylinder, and a cap for sealing the installation tube is installed at the upper end of the installation tube.

[0012] As a preferred technical solution of this utility model, the cover includes a first cover, a second cover and a retaining ring. The first cover and the second cover are spliced ​​together to form a plug. The plug is engaged at the upper end of the mounting tube. The retaining ring is slidably installed at the upper end of the cylinder. The first cover and the second cover have grooves on both sides that match the retaining ring.

[0013] As a preferred embodiment of this utility model, a support plate for stabilizing the ultraviolet lamp tube is slidably installed inside the mounting tube, and an elastic element for providing upward elastic force to the support plate is installed inside the mounting tube.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention connects to the ozone generator pipeline via an installation pipe, and ozone is discharged from the one-way exhaust pipe through the gas chamber. While injecting ozone into the material inside the cylinder for disinfection, ultraviolet lamps disinfect simultaneously. The discharged ozone comes into contact with the installation pipe, cleaning its surface. This solves the problem in existing biocontrol bacteria self-propagation systems where bacteria, viruses, and other microorganisms in the internal material affect the growth and reproduction of biocontrol bacteria when inoculating the bacteria.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-7 This embodiment provides a self-propagation system for biocontrol bacteria in crops, including a cylinder 1. Materials, such as kitchen waste and agricultural residues crushed into a slurry, are placed inside the cylinder 1. After the materials are placed, inoculum is added inside the cylinder 1. A stirring structure can be installed inside the cylinder 1. By stirring the mixture of materials and inoculum, the biocontrol bacteria can propagate and multiply. The stirring structure is not shown in the figure.

[0026] However, in actual operation, it was found that before the inoculum was added, there were many harmful microorganisms such as bacteria and viruses in the material. After the inoculum was added, the harmful microorganisms would affect the growth and reproduction of the biocontrol bacteria. Therefore, in order to reduce or eliminate the harmful microorganisms in the material, ultraviolet lamps were installed inside the cylinder 1.

[0027] Specifically, an installation tube 2 is fixedly installed inside the cylinder 1. The upper end of the installation tube 2 passes through the upper end of the cylinder 1. The installation tube 2 is made of transparent tempered glass. The ultraviolet lamp can be inserted into the installation tube 2. By energizing the ultraviolet lamp, the light from the lamp can pass through the installation tube 2 and irradiate the material inside the cylinder 1, thereby disinfecting the material.

[0028] However, the irradiation range of a single ultraviolet lamp is relatively small. Therefore, four mounting tubes 2 are fixedly installed inside the cylinder 1, and the four mounting tubes 2 are evenly distributed in a circular array. That is, four ultraviolet lamps are installed in the cylinder 1. By using the four ultraviolet lamps in conjunction with the stirring structure, the materials inside the cylinder 1 can be thoroughly disinfected. Of course, the number of ultraviolet lamps is not limited to four. Theoretically, the more ultraviolet lamps there are, the larger the irradiation range, and thus the more comprehensive the disinfection.

[0029] like Figure 4 and Figure 6 As shown, a cap 4 is installed at the upper end of the mounting tube 2. The cap 4 includes a first locking cover 41, a second locking cover 42, and a retaining ring 43. The first locking cover 41 and the second locking cover 42 can be spliced ​​together to form a plug. The plug has an opening in the middle, through which the ultraviolet lamp wire can pass and extend out of the device. The retaining ring 43 has a U-shaped structure and is slidably installed at the upper end of the cylinder 1. A retaining groove is provided on the side of the plug. After the plug is engaged at the upper end of the mounting tube 2, sliding the retaining ring 43 will allow the retaining ring 43 to engage with the outer wall of the groove. The retaining ring 43 can limit the plug and prevent it from detaching from the mounting tube 2.

[0030] Because the stirring structure inside the cylinder 1 vibrates during operation, the ultraviolet lamp located in the mounting tube 2 may shake, potentially damaging it. To secure the ultraviolet lamp in the mounting tube 2, a support plate 5 is slidably installed inside the mounting tube 2. Specifically, an elastic element 51, configured as a spring, is also installed inside the mounting tube 2. The upper end of the elastic element 51 is fixedly connected to the lower end of the support plate 5, applying an upward elastic force to the support plate 5. After the lamp is placed inside the mounting tube 2, a downward pressure is applied to the support plate 5, allowing it to move downward according to the lamp size. At this time, the elastic element 51 is compressed, and the upward elastic force applied by the elastic element 51 to the support plate 5, combined with the locking mechanism, clamps and secures the ultraviolet lamp.

[0031] Further investigation revealed that disinfecting the materials inside cylinder 1 using only ultraviolet lamps was inefficient. To increase disinfection efficiency, ozone was added to disinfect the materials inside cylinder 1.

[0032] Specifically, the installation pipe 2 has an air chamber 21 inside, and the lower end of the installation pipe 2 has multiple exhaust holes that communicate with the air chamber 21. A one-way exhaust pipe 22 is fixedly installed at the exhaust hole at the lower end of the installation pipe 2. The one-way exhaust pipe 22 is a one-way valve with a reference model C2.

[0033] like Figure 2 and Figure 5 As shown, an air pipe 3 is installed between the four mounting pipes 2. The air pipe 3 includes a ring pipe 31, a connecting pipe 32, and an air guide pipe 33. The ring pipe 31 is located inside the cylinder 1, and the stirring shaft of the stirring structure passes through the middle of the ring pipe 31. There are four connecting pipes 32. The air guide pipe 33 and the four connecting pipes 32 are all fixedly connected to the outer wall of the ring pipe 31, and the four connecting pipes 32 are evenly distributed in a ring array. The other end of the connecting pipe 32 away from the ring pipe 31 is fixedly connected to the outer wall of the mounting pipe 2. The air guide pipe 33 has an L-shaped structure. The other end of the air guide pipe 33 away from the ring pipe 31 passes through the upper end face of the cylinder 1, and the air guide pipe 33 extending out of the cylinder 1 is connected to the ozone generator.

[0034] In use, the ozone generator is started. Ozone passes sequentially through the gas guide pipe 33 and the ring pipe 31, and finally enters the gas chamber 21 of the mounting pipe 2 through the connecting pipe 32. It is then discharged from the one-way exhaust pipe 22. The discharged ozone disinfects the materials agitated by the stirring structure inside. As the ozone is discharged, it is compressed by the materials and floats upwards within the cylinder 1. Since the one-way exhaust pipe 22 is located at the lower end of the mounting pipe 2, the floating ozone surrounds the outer wall of the mounting pipe 2. At this time, the ozone generates bubbles within the materials. These bubbles increase the refraction of ultraviolet light, increasing the disinfection intensity of the ultraviolet lamp. Simultaneously, the ozone that comes into contact with the outer wall of the mounting pipe 2 reacts with the surface of the mounting pipe 2, decomposing any materials or microorganisms that may have deposited on the lamp surface. This not only keeps the surface of the mounting pipe 2 clean but also ensures effective ultraviolet emission, improving the efficiency of the ultraviolet lamp.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
